20150296394 | METHOD AND APPARATUS FOR A MODIFIED OUTER LOOP AFTER A RECEIVER OUTAGE EVENT - A method, system and non transitory, tangible computer readable storage medium provides for controlling the BLER (block error rate) in a digital communication system. The outer loop control of the system discounts responses sent by a receiver to data transmission from a transmitter that were sent during a receiver outage event. Either the NACKs or both the ACKs and NACKs sent by the receiver during receiver outage are discounted by the outer loop control which adapts subsequent transmissions by either directly adjusting transmission parameters or by adjusting the selection of transmission parameters. The adapting may be based on individual NACKs and ACKs or after establishing a BLER. | 10-15-2015 |
20150319678 | METHOD AND APPARATUS FOR ANTI-BLOCKING HETNET DEPLOYMENT - A new approach to anti-blocking cellularcommunication for HetNet deployment is proposed. First, a block detector sends a block indicator from an LPN to a scheduler in a macro base station. The scheduler then collects the block indicator statistics of each LPN on a sub-frame basis and updates the statistics in each sub-frame. If the statistics of received block indicators for one sub-frame during an observation period of a specific LPN exceeds a first predefined threshold, then the scheduler will not schedule any more uplink transmission to the LPN during the sub-frame for those UEs which are connected to the LPN. When the statistics of received block indicators becomes less than a second predefined threshold, which is less than the first threshold, the scheduler removes the limitation on uplink transmission to the LPN and allocates the sub-frame of the LPN as usual. | 11-05-2015 |
